MEANS FOR HANDLING BLOOMS.

To all whom it may concern:

Be it known that I, FRANoIs B. UN- OAPHER, a citizen of the UnitedStates, residing at Latrobe, in the county of Westmoreland and State ofPennsylvania, have invented a new and useful Means for Handling Blooms,of which the following is a specification.

This invention has reference to improvements in means for handlingblooms while being subject to the action of a steam hammer, thestructure being particularly adapted for use in foundries.

The object of the invention is to provide means whereby the blooms maybe handled expeditiously and readily transported from one hammer toanother and there manipulated as may be necessary, all the parts beingunder the control of a single operator at a safe distance from thehammer.

The invention comprises, essentially, a supporting structure upon whichis pivotally secured a crane designed especially for the handling ofheavy weights. The swinging arm of the crane is horizontal and the wholestructure is vertically movable by means of a suitable hydraulic lift.The horizontal arm is capable of moving ab out the hydraulic lift as anaxis and carries the various structures for holding the bloom. Mountedupon the crane arm is a pair of jaws adapted to. grasp the bloom, andalso carried by the crane arm is a carriage for supporting dies andother structures designed for the proper forging of the bloom whileunder the action of the steam hammer. The arrangement is such that thecarriage may be moved entirely out of active relation to the bloom andthe latter may be subjected to the action of the hammer without respectto the carriage or parts controlled thereby, and provision is madewhereby the bloom may be turned upon a horizontal axis so as to betreated in different positions by the steam hammer.

The horizontal swinging arm of the crane also carries a supportingstructure for a tool designed particularly for the formation of an eyein the bloom but which supporting member may carry other tools asneeded, such tools being under the control of the steam hammer andcoacting with dies mounted upon the carriage, the structure being suchthat operating tools are carried both above and below the bloom, one ofthe tools being designed to rest upon the anvil of the steamSpecification of Letters Patent.

hammer and support the bloom, while the other tool is carried by astructure under the control of the carriage supporting the firstnamedtool and arranged to be moved into coincidence with the tool or toolsmounted upon the carriage. In this manner the bloom may be subjected tothe operation of suitable tools under the control of the steam hammer sothat various operations may be performed upon the bloom by the steamhammer through mechanism under the control of a single operator.

For convenience of operation several structures are arranged to becontrolled from a single point and by preference electric motors areemployed for effecting the several operations, with the exception of thelifting of the crane bodily through a vertical plane, this lastoperation being preferably performed through the intermediary of asuitable hydraulic lift. Of course the electric motors may be replacedbyhydraulic motors of appropriate form, but electric motors presentadvantages not found in hydraulic motors and overcome certaindisadvantages of hydraulic motors and, therefore, it is preferred thatelectric motors be used wherever practical.

The invention will be best understood by a consideration of thefollowing detail de scription taken in connection with the accompanyingdrawings forming a part of this specification, in which drawings Figure1 is a side elevation, partly in section, of the crane. Fig. 2 is a sideelevation of the crane as viewed from the side opposed to that seen inFig. 1. Fig. 3 is a plan view of the structure. Fig. 4 is a plan view,with parts in section and parts removed, showing the longitudinallymovable carriage. Fig. 5 is a plan view, with parts in section and partsremoved, of the bloom-holding jaws and coacting parts. Figs. 6 and 7 arevertical sections, withparts in elevation, in a longitudinal centralplane through the free end of the crane arm showing different phases ofthe operation of the structure. Fig. 8 is a section on the line A.B ofFig. 6. Fig; 9 is a section on the line D of Fig. 4.

The structure of the crane is large and massive designed for thehandling of heavy weights, and the parts are, therefore, in thepractical embodiment of the invention properly designed for standingstrains incident to the operation of the crane. In the drawings noattempt has been made to show proportions with any exactitude for thiswould necessitate some parts being shown very small, in fact too smallto be intelligible, especially when it is considered that the swingingarm of the crane may be thirty or more feet in length and the uprightmember approaching forty feet in length. It will, therefore, beunderstood that for the sake of clearly illustrating some of the partsthe proportlions of these parts have been exaggerate Referring now tothe drawings, there is shown a post 1 of suitable proportions mountedupon a base 2 which is assumed to be firmly anchored to a suitablefoundation. The post 1 constitutes the stationarymember of a hydrauliclift and also a pivotal support about which the crane as a whole is tobe moved'in a horizontal plane. Fitting the post 1 is a cylindricalcasing 3 formed at the of the cylinder 3.

ottom with a bell 4 into which fits a packing gland 5 confining suitablepacking 6 about the post 1 so that while the cylinder 3 is free to moveboth vertically and circumferentially with relation to the post 1 thegland 5 and packing 6 will prevent the escape of the fluid used in thehydraulic lift. Above the post 1 the cylinder 3 is closed by a cap-plate7 firmly bolted to a flange 8 formed on the top On top of the cap late 7is a short cylinder 9 also firmly secured to the cap-plate 7, and thiscylinder 9 is formed at its upper end with an annular flange 10receiving another cap-plate 11, on top of which is bolted a flange 12011 the lower end of a long tubular structure 13. Within the building inwhich the crane is erected there is formed a horizontal girder 14 at asuflicient height above the floor and which may constitute a member ofone of the roof trusses or which may be otherwise supported. The girder14 has fast therein a cylinder 15, the lower end of which is formed intoa bell 16, and which cylinder receives the upper end of the tubularstructure 13. The bell 16 is provided with a packing gland 17 to renderthe joint between the cylinder 15 and tubular structure or post 13pressure tight, at the same time permitting the post 13 to slip withinthe cylinder 15. The upper end of the tubular post 13 is provided with aperforated annular ange 18 through the center of which is passed a pipe19 extending axially downward through the tubular post 13 to the plate11 through which the pipe 19 opens. The up per end of the cylinder 15 isformed with a gland 20 through which extends the pipe 19, and the latterterminates above the gland 20 in another packing gland 21 into whichthere is passed a smaller pipe 22 extending down into the pipe 19. Thepipe 22 is carried by a yoke 23 fast on the girder 14, and this'pipe 22may come from any suitable source of water supply under pressure.

Fast upon the cylinder 3 is one end of a horizontally projecting cranearm 24 which may be made up of two parallel channel irons 25, 25,extending from the head 26 fast on the cylinder 3, and secured togetherin spaced relation by cross beams 27 wherever necessary.

Mounted upon the arm 24 at a suitable point, say by means of a support28, is a three-way valve 29 of any ordinary construction and so small itis simply indicated in the drawings without any attempt to show thedetail construction. From the valve 29 extend three pipes 30, 31 and 32.The pipe 30 leads to the interior of the tubular post 13. The pipe 31leads to the interior of the cylinder 9 and the pipe 32 leads to theinterior of the cylinder 3 above the post or standard 1.

If water under pressure coming through the pipe 22 and entering the pipe19 is directed by the valve 29 into the upper end of the cylinder 3through the pipe 32, then the reaction between the cap-plate 7 and thetop of the post 1 will cause the cylinder 3 and parts carried thereby,including the crane-arm 24, to be lifted vertically, and this verticalmovement will continue until the valve 29 is turned to the inactiveposition where no more Water may enter the cylinder 3. When it isdesired to cause the crane-arm to descend, then the valve 29 is moved toa position whereby the cylinder 3 anflthe inside of the post 13 areplaced in communication, when the water from the cylinder 3 all escapethrough the perforated upper end of the pipe 13 into the cylinder 15 outof which latter it may flow through an exhaust pipe 33, shown in Fig. 3.As the water flows out the crane arnrwill gravitate to the desiredposition, when the outflow of water may be stopped by moving the valve29 to the proper cut-off position.

Extending laterally from one side of one of the channel beams 25 is aplatform 34 upon which there are mounted in a suitable framework 35 aseries of manipulating levers 36. One of these levers is connected by alink 37 to a bell-crank 38 which in turn is connected by another link 39to the handle 40 of the valve 29. This connection between the respectivelever 36 and valve 29 is to be taken as merely illustrative, since anydesired connection may be employed and may be changed to suit theparticular conditions present in the crane when modified to suitdifferent locations. Mounted upon the platform 34 in suitable relationto the levers 36 is an'operators seat 41.

Carried by the platform 34 by a number of standards 42 upon the ends ofwhich are secured electric controllers 43, are the levers 44 each ofwhich is connected by a link 45 to a respective manipulating lever 36.These controllers may be of any ordinary type used for the propercontrol of electric motors and so simply indicated in the drawingswithout any attempt to show their working parts.

Mounted on the cylinder 3 is a gear wheel 46 with which meshes a pinion47 upon an upright shaft 48 journaled in suitable bearings 49 on one ofthe channel beams and at the end of a post 50. The upper end of theshaft 48 carries a bevel pinion 51 meshing with another bevel pinion 52on an electric motor 53, which is assumed to be coupled up by asufiicient source of power to one of the controllers 43. The electricalconnections are of the simplest kind and being readily apparent to theelectrical engineer they have been omitted from the drawings asunnecessary to the understanding of the present invention. Nor is itnecessary that the exact arrangement of the motor 53 and gear-wheel 46with the intermediate parts should be as indicated in the drawings, itonly being necessary that the motor should be so coupled up to thecylinder 3 that when the motor is energized the crane arm 24 will beswung about a vertical axis. The gear wheel 46 is not fast on thecylinder 3 but simply mounted thereon and is held against rotation by apin or post 54 which may be suitably fixed to the base 2 or otherremovable structure and extends through the gear wheel 46. Thegear-wheel being held against rotation the motor will then cause theswinging of the crane arm around the post 1 as a pivot.

Carried by the outer ends of the channel irons 25 is a slidable carriage55, which as best shown in Fig. 9 may be made of two L-irons 56 joinedby a cross plate 57. Above the L-irons are wearing strips 58 so that thecarriage will fit snugly yet easily within the channel irons 25 forlongitudinal movement therein. The carriage 55 is provided near one endwith a longitudinal central slot 59, at one end of which is formed anabutment 60 fixed to the plate 57 and at the other end the entireabutment 61 may be made up of two plates engaging the opposite sides ofthe plate 57 and held together by a bolt 62 so that this last-namedabutment 61 may be adjusted longitudinally with reference to the slot59. Between the abutment 60 and the other end of the carriage areperforations 63 through the plate 57, one for the reception of a pinblock 64 and the other for the reception of a perforated block 65. Eachof these blocks are of sufficient length to extend a distance below theplate 57, and each is provided with an annular flange 66 normallyresting on the upper face of the plate 57. The purpose of these twoblocks will appear hereinafter.

The carriage 55 has fast to its rear end a screw rod 67 extendingthrough a nut 68 mounted between two cars 69 rising from a cross piece70 fast to the two channel irons 25. The nut 68 is formed with exteriorgear teeth 71 engaged by a pinion 72 on one end of the shaft 73journaled in suitable cross pieces 74 joining the channel irons 25 ontheir upper faces. The end of the shaft 73 remote from the pinion 72carries another pinion 75 meshing with a pinion 76 on the armature shaftof the motor 77 mounted on a suitable cross piece 78 adjacent to thehead 26 of the crane arm. The motor 77 is coupled up to one of thecontrollers 43. The channel irons 25 are connected beyond the crosspieces 74 by other similar cross pieces 79, 80.

Mounted in sliding bearings in one of the cross pieces 74 and in thecross pieces 79 and 80, and capable of moving in the centrallongitudinal plane of the crane arm is a rectangular bar 81, althoughthe bar may be otherwise shaped if so desired, it being, however,important that the bar should not turn on its longitudinal axis. Thisbar terminates beyond the cross piece 80 in a socket head 82, one memberof which has a laterally-extending ear 83 to which reference willpresently be made. The bar 81 carries between the cross pieces 74 and 79a laterally-extending block 84 in'which is formed an internally threadedpassage for the reception of a threaded rod 85 j ournaled at each end inthe cross pieces 74 and 79 and extending beyond the said cross piece 74toward the other cross piece 74, where it is also journaled. Between thetwo cross pieces 74 the rod is reversely threaded from that portionengaging the block 84, as indicated at 86, and this reversely threadedportion extends through an internally threaded block 87 fast on the endof a sliding bar 88 of rectangular or other suitable shape mounted toslide in suitable bearings in the cross piece 79 and adjacent crosspiece 74. The bar 88 is parallel to the bar 81 and its outer end 89beyond the cross piece 79 is turned outward and is there secured toanother bar 90 parallel with the bar 81 but spaced therefrom to agreater extent than is the bar 88. The bar 89 is also preferablyrectangular in cross section and has a sliding bearing in the crosspiece 80, which is extended laterally to one side of the correspondingchannel iron 25 for the purpose of supporting the bar 90. The outer endof the bar 90 is appropriately curved and bent to form a jaw 91 opposedto the head or jaw 82 on the end of the bar 81. The two jaws 82 and 91constitute the clamping and holding means for a bloom which is simplyindicated at 92. The jaw 91 has its free end extended laterally, asshown at 93, and there formed with a conical tooth 94.

Mounted at one end in the car 83 is a shaft 95 having a spur head 96beyond the car 83 in line with the tooth 94. This shaft is continuedbackward parallel with the bar 81 and extends through a collar 97 journaled in the cross piece 79. The shaft 95 is provided with anelongated spline 98 whereby the shaft is capable of sliding movementthrough the collar 97 but is constrained to rotate with said collar. Thecollar 97 carries a gear wheel 99 meshing with a pinion 100 on thearmature shaft of a motor 101 suitably mounted on the adjacent channelbeam 25. This motor is coupled up to one of the controllers 43. Thescrew rod 85 beyond its journal bearing in the cross piece 74 nearest tothe pivot end of the crane arm carries a pinion 102 meshing with anotherpinion 103 on the armature shaft of a motor 104 suitably mounted on thecross piece 7 8 and which is under the control of one of the controllers43. The cross pieces 79 and 80 each carry uprights or standards 105 and106, respectively, and in the upper ends of these two standards isjournaled a shaft 107 best shown in Figs. 6, 7 and 8, and this shaftbetween its journal bearings carries a gear wheel 108 meshing with apinion 109 on the arm shaft of the motor 110 suitably sup orted on apost 111 fast on one of the journa beams 25. The outer ends of the shaft107 carry worms 1 12 in suitable housings 113 on top of the standards105, 106. The worms 112 each engage a worm-gear 114 on an uprightvertical shaft 115 extending downward to a journal bearing in thecorresponding cross piece 79 or 80. Below the worm-gear 114 the shaft115 is threaded and passes through a suitably threaded erforation in ablock 11.6 sliding in channe s 117, 118, on opposite sides of thestandards 105 or 106. The blocks 116 are formed with sliding bearingsfor a bar 119 immediately over the clamp bar 81. This bar 119 has itsouter end formed into an eye 120 for the reception of a punch block 121formed with a suitable head resting on the eye and with an extension 122constituting the punch end of the block. Between the standards 105 and106 the bar 119 is provided with a downwardly-extending arm 123 reachinginto the slot 59 of the plate 57 and in the path of the abutments 60 and61. This arm 123 is also slotted, as indicated at 124 for the passage ofthe bar 81, the said arm straddling the bar 81.

The outer or free end of the arm 24 is supported. by brace rods 125extending to a col ar 126 fast on the tubular post 13.

Let it now be supposed that it is desirable to operate the crane for thepurpose of carrying a bloom from one hammer to another hammer, the anvil127 and hammer head 128 of which is diagrammatically represented inFigs. 6 and 7. For this purpose the operator upon the seat 41 willmanipulate the proper levers 36 to withdraw the carriage to its fullestextent into the swinging arm of the crane. W hen this occurs theabutment engages the arm 124 on the bar 119 and withdraws the eye 120until in engagement with the standard 106. The motor 110 is energized inthe proper manner to cause the bar 119 to be lifted to its fullestextent carrying the block 120 with it. The motor 104 is also energizedto cause the intermediate jaws 82 and 91 to open to the requisiteextent. Now, the motor 53 is energized .to cause the crane to swingabout its pivot support until in proper relation to the hammer, and abloom brought out from the furnace is then moved between the jaws 82 and91 and the motor 104 is caused to be actuated in a suitable manner tobring the jaws toward each other and so properly grasp the bloom 92.Either before or after this has occurred, the valve 29 has been somanipulated as to cause the crane arm to be lifted to the properelevation. Now the carriage 55 is moved outwardly until the block 64 oris brought immediately under the bloom and because of the engagement ofthe arm 123 with the abutment 61 the block 121 is moved into coincidencewith the block 65, if that be the block then under the bloom. If it bedesired that the block 64 be the active block, then the carriage ismoved backward until the said block 64 is directly under the bloom, theother block 121 remaining quiescent because of the slot 59 in thecarriage 55 permitting said carriage to move without engaging the arm123. The crane is swung around by the action of the motor 53 until thedesired block 64 or 65 is immediately over the anvil 127 of the steamhammer. Now, the crane arm is permitted to drop until the block 65, ifthat be the active block, is engaged by the anvil 127 and pushed upwardabove its seat on the carriage. The rod 1 19 is now lowered by theaction of the motor 110 until the active end of the block 121 is restingon the bloom and the eye 120 is just above the bloom. If it be designedto punch a hole in the bloom then the steam hammer is brought down withthe requisite force upon the block 121 and the end 122 will punch a holethrough the bloom, the block 65 acting as a die, it also being assumedthat the bloom is not too thick. hen the block 64 is utilized then thebloom is entered from both directions toward the center when the steamhammer is brought into operation.

Suppose, now, that it be desirable to turn the bloom over eitherpartially or wholly, then in order that the bloom may be gras ed by asuitable crane or by the withdrawa of the carriage and parts acting inconjunction therewith the bloom may be permitted to rest upon the anvilof the steam hammer. When the bloom is properly supported the jaws S2and 91 are moved apart and the i crane arm is swung to one side untilthe tooth 93 and center 96 are in diametric relation to the bloom, whenits jaws may be again brought together until the tooth 93 engages oneside of the bloom and the spur center 96 engages the other side of thebloom. Now, the crane arm is elevated sufficiently and the motor 101 isput into motion causing the bloom to rotate because of the rotation ofthe spur center 96. After the bloom has been turned to the proper extentit may be again grasped by the jaws 82 and 91, as before, and furtheroperation be performed upon the bloom, as desired.

It will be seen that with a structure such as described a bloom may becarried from the furnace to the steam hammer and brought by the latter,as designed, with all the operations, so far as the crane is concerned,under the control of one operator.

Since the jaw 91 is of considerable length it is liable to springbetween the bearings in the cross pieces 79 and 80, and for this reasonthe lateral extension 89 has fast thereon a downwardly-direeted member129, which member is again extended horizontally, as shown at 130, andmoves in guideways 131 fast on the corresponding channel 25.

It is advisable that the operator should have some means of determiningthe exact position of the blocks 64 and 65. For this reason there isformed on the under side of the carriage 55 two teeth 132, 133. In thepath of these teeth is a ivoted hook 134 fast in the fixed portion ofthe crane arm, and this hook is under the control of the pivoted pawl135 connected by a link 136 to a bellcrank 137 and the latter isconnected by a link 138 to a presser head 139 within reach of the footof the operator seated in the seat 41. When the operators foot ispressed upon the head 139 then the hook 134 is moved upward into thepath of one of the teeth 132 or 133. If the carriage be in its retractedposition then the hook will engage the tooth 133 and stop the carriagewhen the block 64 has reached the operative position. If the operatordesires to stop the carriage when the block 65 has reached the operativeposition, then the hook 134 is moved into position and into the path ofthe tooth 132 after the tooth 133 has moved beyond operative relation tothe hook 134.
